BACKGROUND: Chronic total occlusions (CTOs) are present in more than one third of older patients with myocardial ischemia, but controversy remains about the best therapeutic approach. AIMS: To compare long-term survival after CTO revascularization (percutaneous coronary intervention [PCI] or coronary artery bypass graft [CABG]) versus medical treatment (MT) alone in patients aged 75 and older. METHODS AND RESULTS: A total of 1,252 consecutive patients with at least one CTO were identified from 2010 to 2014 in our center. Patients were stratified by age (<75 years vs. ≥75 years) in the present analysis. All-cause and cardiac mortality were assessed at a median follow-up of 3.5 years. In the older subgroup (26%), patients were more likely to be treated with MT alone (71% vs. 43% of younger patients; p < 0.001). Patients undergoing revascularization were younger and had higher left ventricular ejection fraction (LVEF) and lower age, creatinine, ejection fraction (ACEF) score (age/LVEF +1 if creatinine >2.0 mg/dL), compared to the MT group (p < 0.05). As compared to MT, revascularization predicted lower rates of cardiac mortality and all-cause mortality in older patients, both in the subgroups treated with CABG (hazard ratio [HR] 0.35, 95% confidence interval [CI] 0.17-0.71; HR 0.39, 95%CI 0.18-0.81) and PCI (HR 0.57, 95%CI 0.33-0.98; HR 0.59, 95%CI 0.28-1.2). No differences in mortality were observed according to type of revascularization procedure. CONCLUSIONS: Among patients aged at least 75 years with a CTO, revascularization (PCI or CABG) rather than MT alone may portend a better outcome in terms of all-cause and cardiac mortality.
